Lucky bastard
Sure do
( id have to read the rules once again though haha )
Added you to the list in post #3
No. Light has an inverse square with distance. You have a couple factors fighting you, one is resisatance. Your optics and the water column slow the light. Two is LEDs don't dim in a linear fashion, not to mention each led will dim differently than one made by a different company or in a different wavelenght. The only way to know par with an confidance is to measure.
Is there also spectrum change with the dimming? (I might have heard this from you before.)
yes, but it's more extreme when comparing the LEDs at full power and low power (ex below 25%) From my initial testing with the spectrometer, the lights I've tested from 50% power to 100% power aren't seeing much spectral shift. The spectrum gets a bit narrower at 50% compared to 100%, but otherwise it's quite close. Below 25% each LED I've tested can shift a fair amount depending on the led wavelenght or by manuf.
Exactly my concern, I bought an overpowered light fixture and need to run at a very low % of max output. Thanks.
